Use tilt to get the plane of focus exactly where you want it and then use keystone correction in software to reintroduce a believable perspective. You could use focus stacking for a similar effect, but it is messy and frankly I think it is difficult to attain the same quality.
When we made the keystone tool in Capture One we found that an 80% correction (the default) is usually a good amount. This means that you only need to "undo" about 20%, so you won't loose much of your crop.
In fact you may get a slightly larger crop than you otherwise would. The top of the image tends to be sky which is easy to fill in (e.g. content aware fill).
